Adaptive zero output impedance converter

A display system for an electronic device, the display system comprising:

• a display panel;
• a power supply including a power management integrated circuit and one or more external passive components;
• a filter coupled to the output of the power supply, the filter comprising an inductance and an associated parasitic resistance;
• and
• a power delivery network coupled between the filter and a power input of the display panel;
• wherein:
• the power management integrated circuit includes compensation circuitry that receives a signal corresponding to an output current of the power supply and generates therefrom a current compensation signal that is combined with a voltage feedback signal sensed between the filter and the power delivery network;
• and
• the combined voltage feedback and current signal is provided to control circuitry that generates drive signals for one or more switching devices that cooperate with the one or more external passive components to generate an output voltage for delivery to the display panel via the filter and power delivery network;
• and
• the compensation signal causes an increase in the output voltage responsive to an increase in the output current.
